Maps

A great place to start is the Tour of Go: Maps. It's short, clear, and beginner-friendly.

The Go team has a great blog post that explains maps in more detail: Go maps in action.

There's also a nice deep dive video in Russian: Как на самом деле устроен тип Map в Golang?.

Source code: runtime/map.go on go.dev.

Examples: Maps on Go by Example.
